i race in Australia at SMA and nobody runs a 416 in 540 class. I have a 415msx and there is a couple of them and cyclones and other like ta05, the only reason i dont have a 416 is because the motor doesnt fit and the 415msx does me well. the guy who wins most of the time runs an original 415. maybe nexy year ill get a 415we when i step up to stock
